' Application led May 8, 1911. Serial No. 625,504.

To all 'whom t may concern:

Be it known that I, VICENTE FoN'r, a citizen of the Republic of Cuba, residing at Calle B No. 74, Vedado, Habana, Cuba, have invented new and useful Improvements in Floor and Roof Constructions, of which the following is a s ecification.

This invention re ates to building construction and more particularly to the combination of members arranged to resist the transverse stresses liable to be subjected thereto, such as floor and roof constructions.

It comprises a plurality of suitably supported members spaced apart from each other, such as I beams or built up girders, and a plurality of spanning members adapted for support by such members, and so constructed as to transmit the loads coming thereupon to the supports, the disposition of the parts being such that they may be Wholly or partly covered by fire resisting material, such as concrete, where such is desirable.

The objects of my invention are to provide such a construction which is light, durable and easily assembled, with the parts disposed to form a rigid construction and thus serve as a wind brace to the structure as well as a construction free from vibration. I attain these objects by the construction and the arrangementof parts illustrated in the accompanying drawings, in which,-

Figure 1 is a sectional view through a floor construction taken longitudinally with the spanning members; Fig. 2 is a plan view of a portion of floor construction, parts being broken away to show the relation of the members one to another; Fig. 3 is a perspective view showing one of the spanning members supported by `an I beam; Fig. 4 is a central transverse section through one of the spanning members; Fig. 5 is a side elevation of one of the spanning members showing its relation to the supporting I beam, and Fig. 6 is a sectional view taken substantially at the neutral axis of one of the spanning members.

In the drawings, 1 represents an I beam having the usual web 10, compression flange 8 and tension flange 14.. Adapted for support by the I beams are spanning members 2 made up of various concrete compositions, terra cotta or the like, each having a central longitudinal web 5, a compression flange 6 and a tension flange 7. It is also desirable that, especially in the case of relatively long spanning members that such be provided with central transverse bracket-like webs 16 under the upper flanges 6.

As shown in the drawings, spanning members 2 may be provided with reinforcing sus ension means such as the tension rod 17, em edded in the tension flange 7 and looped into, and extending from the compression flange 6.

In order to form supporting means for the spanning members, the compression and tension flanges of their respective members merge into one another at preferably the neutral axis of the member, forming outstanding portion `for engagement with the flanges 14, and are referably formed at each end with an inclined face 4, a vertical face 3, a bearing face 11 and an inclined wedge face 12.

In order to assemble the spanning members between the su ports 1, the spanning members are relative y reduced in length so that, when in place, a space 13 is left between the vertical face 3 and the web 10 of the I beam. This space 13 allows for expansion and contraction of the spanning members.

Vith reference to Fig. 1 of the drawing, the I beam is shown surrounded by a wedge shaped filling 9 of fire resisting material,

such as cinder concrete, which is leveled ofl" as at 18 to the floor level, the space under the tension flange of the I beam being protected by a wedge-shaped formation of cement-like material 15, which is held in lace, when set, by the inclined faces 12 ofD the spanning members. The wedge shaped filling 9 embeds the extending portions of reinforcing rods 17 and, should the outstanding portions formed at the juncture of the upper and lower flanges become ruptured, the structure will remain stable through the wedging position of the filling 9 adjacent the ends of the spanning members.

From the foregoing description it is made manifest that I provide an economical and substantial floor and roof construction, the spanning members of which, owing to their relatively reduced length with respect to tbe spacing of the supporting member, are readily assembled in place as shown in Fig. 3.

In floor and roof construction, the combination of I- shaped supporting beams spaced apart from each other, an -shaped merge into the end face of said member at the neutral axis thereof, and having its opposite ends formin outstanding portions which are supporte upon the lower flanges of said beams, said spannin member being relatively reduced in lengt with respect to the spae'ing'o the supporting beams so as to leave spaces between the end faces of said outstanding portions and thejs'ebs of said supporting beams, reinforeingsuspension means embedded in the lower flange of said spanning member vand alined with the nemers i l central longitudinal web thereof and extend I shaped llings between the webs of said beams and said inclined portions of said upper flanges and embedding the extending en s of the reinforcin suspension means, substantially as and or the purpose set forth. v In testimony whereof l have axed lmy signatureiin presence of two witnesses.
